Does the president have to be sworn in on a Bible?

A. The president can be sworn in on any book that he or she chooses. While the majority of U.S. presidents have chosen Bibles, there have been a handful of exceptions over the years. Franklin Pierce and John Quincy Adams were sworn in on law books, which were meant to represent the U.S. Constitution. Theodore Roosevelt refused to use any book or other prop when he was sworn into office.
